Chemical filtration of ketoprofen from water with a biohybrid PVA–BSA membrane. (a) Electrospun membrane is placed in a filter module and then mounted on the syringe tip with a Luer Lock connection. (b) Chemical structure of ketoprofen used as the target in the filtration experiments. (c) Normalized quantities of ketoprofen filtered from a solution of 26 μM concentration with respect to the weight of the membrane are zero for the pure PVA membrane and 550 ± 100 μg/g for the 12 wt % PVA–10% BSA biohybrid membrane.
